Product Description

The 1002580535 Engine Repair Kit for WP10/WD618 is a comprehensive maintenance set designed for Weichai WP10 and WD618 diesel engines-used in heavy-duty trucks, engineering machinery, and generator sets. It includes key wear-resistant and sealing parts: piston rings, valve seals, main/connecting rod bearings, oil seals, gaskets, etc. It restores engine performance, solves oil leakage, power reduction, and high fuel consumption caused by component wear/aging, and extends engine life. We use high-quality materials and precise manufacturing: piston rings are chrome-plated ductile iron-wear-resistant and oil-controlled. Valve seals are high-temperature silicone rubber-sealing and anti-aging. Bearings are high-lead alloy-wear-resistant and shock-absorbing. Gaskets are multi-layer steel with rubber coating-high-pressure resistant and leak-proof. All components' dimensions and interfaces fit the original WP10/WD618 engine exactly, so assembly requires no mods. It handles tough conditions-400℃ cylinder heat, 2200rpm crankshaft speed, 5-600Hz vibration-without component deformation, seal failure, or bearing ablation. Installation follows standard maintenance: disassemble the engine, replace worn parts with kit components, assemble with proper torque/clearance, and test run. Before shipping, each component is strictly inspected: dimensional accuracy, hardness, sealing, and fatigue-so it's reliable. We've supplied to 70+ Weichai after-sales, repair shops, fleets for 12 years-users praise its precise matching and reliable performance.

Advantages

①Comprehensive & matched: Includes all key maintenance parts-no need to buy separately. Saves 50% procurement time vs single-component purchase.

② High-quality & durable: Premium materials + precision manufacturing ensure wear resistance/high-temperature resistance. Component life 35% longer than ordinary repair kits.

③ Perfect for WP10/WD618: Made to original engine design-all components fit exactly. No modification needed during assembly-reduces maintenance difficulty by 40% vs universal kits.

④ Restores engine performance: Professional matching optimizes sealing and power transmission, solving oil leakage/power reduction/high fuel consumption-restores power and fuel economy to factory level.

Usage

This Engine Repair Kit (Model: 1002580535) is only for Weichai WP10 (WP10.5H, WP10.336) and WD618 (WD618.350, WD618.420) diesel engines-used in heavy-duty trucks, engineering machinery, generator sets. It won't work on other Weichai series (WP7, WP12) or non-Weichai engines (Yuchai YC6K, Xichai 6DL). Those have different structures, component sizes, and installation needs-this kit won't fit or work.

FAQ

Q1: Works on Weichai WP12 engines?

A1: No-WP12 has different structure/sizes. It causes component mismatch, leading to engine failure or damage. Get the WP12-specific repair kit instead.

Q2: Engine still leaks oil after using the kit?

A2: First check installation (gasket position correct, bolts tightened to specified torque). If good, clean/repair engine mating surface (remove impurities/damage). If mating surface is intact, replace damaged kit components. Still leaking? Contact after-sales.

Q3: How to store unused kit components?

A3: 1. Store in dry, ventilated, dust-free environment; 2. Keep sealed in original packaging; 3. Avoid high/low temperatures; 4. Use within 2 years of purchase.

Q4: Need to replace all kit components during maintenance?

A4: Not mandatory but recommended. Kit components are professionally matched-replacing partial parts causes mismatched wear. For best results, replace all key components during overhaul.
